Souyouz leaking. I think I'm right in saying this is the 'taxi' back for the spacestation?
Another question: are liquid particles like solid particles - i.e. are they 10,000 miles an hour junk that can damage other things in space.
Scott manley on YouTube has covered it. (Space geek,)
It might be cooling fluid one option is they might just try to get back home in it.
Well you know what it is like, you go out for (space)walk in the evening and it is colder than you think. Suddenly you get caught short and have to have a wee behind the nearest space module. It has happened to us all, I am sure.

They'll not be liquid for long. If they're in shade they'll freeze more or less instantly and behave like any other solid while that state persists. As soon as they're hit by sunlight they'll boil off into gas and disperse.

what's the physics? A liquid boils when its vapour pressure is the same as the atmoshpheric pressure around it, and as space is basically a vacuum, I assume that's pretty readily achieved. However, the temperature is pretty cold (2.7K I just googled) so do those rules still apply?
The temperature in the sunlight is higher - same sunlight as we feel on the planet but not filtered through the atmosphere, the infrared heats anything it hits. Technically a solid transitions to gas by sublimation, not boiling, but same effect.
I get that, about it getting hot in sunlight - although technically I think it would still go through a liquid phase, just that would be so short that to all intents and purposes it goes direct to gas.
I mean the freezing bit. It's liquid as it leaks out, and assuming it's not in sunlight will cool to the temperature of the surrounds, which would suggest it becomes solid. As johnners said:

I don't know if that's right, because competing with that, as it's a vacuum, it'll still boil even at very low temperatures because the vapour pressure will still be higher than the surrounding pressure which is around 10^-16 bar, pretty damn close to zero.
So what's the physics that decides whether it solidifies or boils? I mean, the whole spaceship doesn't just boil away.......
